10 Evaluation Analysis Activities
The evaluation analysis activities involved a structured evaluation of Pivotal tc Server,
including the following areas:
Development: The evaluators analyzed the Pivotal tc Server functional specification and
design documentation; they determined that the design completely and accurately describes
the TOE security functionality (TSF) interfaces, the TSF subsystems and how the TSF
implements the security functional requirements (SFRs). The evaluators analyzed the Pivotal
tc Server security architectural description and determined that the initialization process is
secure, that the security functions are protected against tamper and bypass, and that security
domains are maintained. The evaluators also independently verified that the correspondence
mappings between the design documents are correct.
Guidance Documents: The evaluators examined the Pivotal tc Server preparative user
guidance and operational user guidance and determined that it sufficiently and
unambiguously describes how to securely transform the TOE into its evaluated configuration

and how to use and administer the product. The evaluators examined and tested the
preparative and operational guidance, and determined that they are complete and sufficiently
detailed to result in a secure configuration.
Life-cycle support: An analysis of the Pivotal tc Server configuration management system
and associated documentation was performed. The evaluators found that the Pivotal tc Server
configuration items were clearly marked. The developer’s configuration management system
was observed during a site visit, and it was found to be mature and well-developed.
The evaluators examined the delivery documentation and determined that it described all of
the procedures required to maintain the integrity of Pivotal tc Server during distribution to
the consumer.
The evaluators reviewed the flaw remediation procedures used by Pivotal, Inc. for the Pivotal
tc Server. During a site visit, the evaluators also examined the evidence generated by
adherence to the procedures. The evaluators concluded that the procedures are adequate to
track and correct security flaws, and distribute the flaw information and corrections to
consumers of the product.
Vulnerability assessment: The evaluators conducted an independent vulnerability analysis
of Pivotal tc Server. Additionally, the evaluators conducted a search of public domain
vulnerability databases to identify Pivotal tc Server potential vulnerabilities. The evaluators
identified potential vulnerabilities for testing applicable to Pivotal tc Server in its operational
environment.
All these evaluation activities resulted in PASS verdicts.
11 ITS Product Testing
Testing consists of the following three steps: assessing developer tests, performing
independent functional tests, and performing penetration tests.
11.1 Assessment of Developer Tests
The evaluators verified that the developer has met their testing responsibilities by examining
their test evidence, and reviewing their test results, as documented in the ETR2
.
The evaluators analyzed the developer’s test coverage analysis and found it to be complete
and accurate. The correspondence between the tests identified in the developer’s test
documentation and the functional specification was complete.

11.2 Independent Functional Testing
During this evaluation, the evaluator developed independent functional tests by examining
design and guidance documentation, examining the developer's test documentation,
executing a sample of the developer's test cases, and creating test cases that augmented the
developer tests.
All testing was planned and documented to a sufficient level of detail to allow repeatability
of the testing procedures and results. Resulting from this test coverage approach is the
following list of CGI IT Security Evaluation & Test Facility test goals:
a. Repeat of Developer's Tests: The objective of this test goal is to repeat a subset of the
developer's tests;
b. Identification, Authentication and Access Control: The objective of this test goal is to
confirm the TOE’s Identification, Authentication and Access Control meets the
requirements of the ST;
c. User Lookout: The objective of this test goal is to confirm that the TOE will correctly
enforce the session disconnect; and
d. Thread Quotas: The objective of this test goal is to confirm that the TOE properly
enforces the maximum number of connections as claimed by the ST.
11.3 Independent Penetration Testing
Subsequent to the independent review of public domain vulnerability databases and all
evaluation deliverables, limited independent evaluator penetration testing was conducted.
The penetration tests focused on:
a. Port Scan: The objective of this test goal is to scan the TOE using a port scanner to reveal
any potential avenues of attack;
b. HTTP Interface: The objective of this test goal is to verify exploits against HTTP
interfaces;
c. Tomcat transfer: The objective of this test goal is to verify exploits against the Tomcat
Transfer Encoding Module; and
d. Weak Passwords: The objective of this test goal is to confirm the TOE will not allow the
usage of weak passwords.
The independent penetration testing did not uncover any exploitable vulnerabilities in the
intended operating environment.

The detailed testing activities, including configurations, procedures, test cases, expected
results and observed results are documented in a separate Test Results document.
11.5 Testing Results
The developer’s tests and the independent functional tests yielded the expected results,
giving assurance that Pivotal tc Server behaves as specified in its ST and functional
specification.
12 Results of the Evaluation
This evaluation has provided the basis for an EAL 2+ level of assurance. The overall verdict
for the evaluation is PASS. These results are supported by evidence in the ETR.
13 Evaluator Comments, Observations and Recommendations
The evaluator notes that the usage of this product does not mitigate against a number of
threats that would be encountered on an untrusted network. Potential consumers of this
certification are encouraged to review the scope of the evaluation and the security claims that
are made within the security target.
The evaluator also encourages potential customers to subscribe to product updates from the
vendor. While the process of providing updates is possible to change in the future, the
evaluator noted a robust infrastructure from a mature vendor for the mitigation of bugs and
security flaws.
